Is there a way to drain the half of the coolant that remains in the engine? My old saabs had drain plugs on the blocks.

Here is a post that explains where the 1zz& 2zz block drains are.I flush/refill my system 3 times with distilled water using the radiator drain plug only.http://forums.genvibe.com/zerothread?id=16641
